Njira yozimitsira, zowonjezera za ulimi, mpeni wotsekereza kwambiri, kuuma kwambiri, komanso kusweka

Kufotokozera Kwachidule:

Mpeni wolima umapangidwa ndi chitsulo cholimba kwambiri chomwe sichingawonongeke, ndipo m'mphepete mwake mwachikale mwakhala mukuchitapo kanthu pa kutentha kwapadera, zomwe zimapangitsa kuti ukhale wakuthwa komanso wosawonongeka. Woyenera kulima, kumasula, komanso kudula mizu pamitundu yosiyanasiyana ya nthaka. Kapangidwe kake kapadera kopindika kamachepetsa kukana ndipo kamawonjezera mphamvu yosweka kwa nthaka. Kosavuta kuyika, kogwirizana ndi ma rotary tillers osiyanasiyana ndi makina a ulimi, zomwe zimapangitsa kuti ntchito igwire bwino ntchito komanso ubwino wa kulima.

Chogulitsachi chapangidwa kuti chigwiritsidwe ntchito m'malo ovuta monga kukonzanso malo otayirako zinyalala, kufukula nkhalango, kugawikana kwa nthaka yolimba, ndi miyala yosasunthika. Ndicho chowonjezera chachikulu cha mathirakitala akuluakulu, zokumba, ndi zida zozungulira zolima. Poyankha mavuto omwe zida zodulira zakale zimatha kusweka m'malo amchenga ndi miyala, kumamatira m'malo a dothi, komanso kukodwa m'zitsamba, tagwiritsa ntchito njira ziwiri zopezera "biomimetic streamline" ndi "high-strength alloy materials" kuti tipeze nthaka yolowera bwino komanso yolimba kwambiri m'malo ogwirira ntchito kwambiri.

Thupi la tsamba limapangidwa ndi chitsulo cha boron ndi matrix yachitsulo cha manganese, ndipo limapangidwa ndi kupangira kutentha kwambiri pa 1200 ℃. Pophatikizidwa ndi ukadaulo wolimbitsa wa multi-element co infiltration, kuuma kwa pamwamba kumatha kufika HRC 48-52, pomwe pakati pake pamakhala kulimba kwambiri kuti pasasweke. Mphepete mwa tsambalo limalumikizidwa ndi wosanjikiza wosagwiritsidwa ntchito wa tungsten carbide, womwe uli ndi kukana kowirikiza katatu kapena kasanu kuposa mipeni yachitsulo ya 65Mn wamba ndipo ndi woyenera kugwiritsa ntchito zinthu zolemera zokhala ndi miyala kapena mizu ya mitengo.

Tsamba lothyola dothi lopindika: kugwiritsa ntchito kapangidwe kopindika kosalunjika, kuchepetsa kukana kulowa m'nthaka, kuchepetsa mphamvu yodulira ndi 20%, ndikugwiritsa ntchito mphamvu ya centrifugal kuti igwedeze dothi lokha, kupewa "kumatirira tsamba".

Kulimbitsa kufalikira kwa mphamvu: Tsamba lakumbuyo limakhuthala ndipo lili ndi mipata yotulutsira zinthu kuti lifalitse katundu wogundana komanso kuti lipewe ming'alu ikagunda miyala kapena matabwa amatabwa.

Mawonekedwe oyika onse: Malo okhazikika a mabowo a bolt, omwe amagwirizana ndi mitundu yayikulu ya zogwirira za rotary tiller blade pamsika (monga Leiken, Dongfanghong, ndi zina zotero), amatha kusinthidwa mwachangu popanda kusintha.
